Quick recap
1558. Ned Willard, a tolerant Protestant from Kingsbridge, loves the Catholic Margery Fitzgerald, but her family marries her off to Bart Shiring. Ned enters Elizabeth I's service and becomes the queen's spymaster. In Paris, Sylvie Palot, a Protestant bookseller's daughter, risks her life for her faith, while the Catholic Pierre Aumande plans the St. Bartholomew's Day massacre. Margery's brother Rollo becomes an exiled priest and plots against Elizabeth as Jean Langlais. Ned uncovers the Babington Plot, which sends Mary, Queen of Scots, to the block, helps defeat the Spanish Armada and, in 1605, stops the Gunpowder Plot, Rollo's scheme, at the last moment. Margery finally ends up with Ned.
